ADJUSTABLE BRACKET CONSTRUCTION Filed May 24, 1955 INVENTOR ATTORNEY Bye/y a We a// Patented Mar. 23, 1937 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to supports for rollers such as those upon which maps or window shades are commonly mounted.

One of the objects of this invention is to provide such supports which may be easily adjusted to accommodate rollers of varying length and which are held against accidental displacement from their adjusted position.

Another object of the invention is the provision of such supports wherein the fixed member and movable members are of simple form and may be readily produced at low cost.

Another object of the invention is the provision of brackets adjustably mounted on a suitable support, such as a molding, said brackets being so constructed that they are held in positive adjusted position by the aid of a simple and inexpensive construction.

This invention possesses many other advantages, and has other objects which may be made more easily apparent from a consideration of several embodiments of the invention. For this purpose there are shown a few forms in the drawing accompanying and forming part of the present specification. These forms will now be described in detail, illustrating the general principles of the invention; but it is to be understood that this detailed description is not to be taken in a limiting sense, since the scope of this invention is best defined by the appended claims.

Referring to the drawing:

Figure 1 is an isometric view showing one of the improved supports mounted on a wall with one end of a roller in place in the movable I bracket;

Figs. 2 and 3 are sections on an enlarged scale as seen on correspondingly numbered planes of Fig. 1;

Fig. 4 is a front elevation, also on an enlarged scale, of the roller and support of Fig. 1;

Fig. 5 is a cross-sectional view of a slightly different form of the fixed member;

Fig. 6 is an isometric view of a modified form of the movable bracket; and

Fig. 7 is an isometric view of another modified form of the movable bracket.

Referring more particularly to the drawing, a roller 8 may have a map, chart, or the like, 9 carried on it. A supporting pintle l0 extends from one end of the roller and fits in a suitable opening I I, such as a slot or aperture formed in a projecting ear l2 on the movable bracket l3. A similar supporting pintle and bracket will, of course, be provided at the opposite end of roller 8.

If roller 8 is a spring-roller, such as is common- 1y used, the supporting pintle H1 at one end will be square or fiat and the opening I l shaped correspondingly.

Bracket l3 as will be noted from an inspection of Fig. 2 is of an inverted U or channel shape, having an outside leg 14 upon which the ear [2 is formed, and an inside leg l5. The inner leg is longer than the outer leg and reduced in width, terminating in the depending extension Hi. The fixed or stationary member Il may be formed of a strip or narrow plate of metal I8 having a bottom flange or inturned leg I9. It may extend continuously between the brackets and the desired distance beyond each, or it may be only a short section at each bracket of sumcient length to permit the desired range of adjustment.

Member I! is mounted on a cooperating moulding or plate 20 which may be made of wood. Countersunk head wood screws 2| can be provided with separators 22 serving to hold the strip l8. in spaced relationship therewith (Fig. 3) This forms an upright U or channel 24 upon the upper edge of the outer leg of which the bracket i3 is adapted to rest. The bottom flange 19 has cut out portions or slots 23, adapted to receive the extension I6 (Fig. 4). This of course must be of such length as to extend slightly through the opening 23 when bracket I3 rests on the edge of leg I8. Molding 20 is secured on wall 25 in any convenient manner.

It will be plain from an inspection of the drawing that bracket l3 may be easily shifted longitudinally along the stationary member by raising it a short distance to bring extension l6 out of opening 23. As legs l4 and I5 of the movable bracket continue to embrace the leg l8, this adjustment is rendered easy. The fineness of the adjustment will depend on the spacing of the openings or slots 23. The weight of the roller etc., resting on the bracket will serve to hold extension IS in its opening, thus preventing accidental displacement of the bracket l3.

In Fig. 5 is illustrated a different form of support for the bracket l3. In this form, a U-shaped metal strip 26 provides the channel 24, the outer leg 21 functioning as leg l8 in the previously described form, and the inner leg 28 being secured directly to the wall 25 as by screws 29. Thus the wood molding 20 is eliminated. Openings 30 are provided in the bottom of the channel to engage extension l6.

Fig. 6 shows a modified form of bracket 13 having a pair of openings 1 I, whereby two rollers may be supported, one behind the other. By increasing the length of ear l2 more openings may be provided to support additional rollers, if desired.

Fig. '7 shows another modification of bracket IS in which ear 12 previously described is formed as a hook 3| from which drapes or the like may be hung. Of course, other forms of hanging attachments could be utilized.

I claim:

1. In a device of the character described, a supporting trough open at the top and having spaced apertures in the bottom of the trough in combination with a sheet metal bracket comprising a folded U-shaped portion, the legs of said U-shaped portion being adapted to straddle one side of the trough, the inner leg being adapted to extend into any one of said trough apertures,
